Vedclass · Answer

(D) In cellular respiration,$NAD^+$ is reduced to $NADH + H^+$ during several steps of the Krebs cycle and the link reaction.$1$. Pyruvate $\rightarrow$ Acetyl coenzyme $A$: This step involves the enzyme pyruvate dehydrogenase and reduces $NAD^+$ to $NADH + H^+$.$2$. Isocitric acid $\rightarrow$ $\alpha$-Ketoglutaric acid: This step is catalyzed by isocitrate dehydrogenase and reduces $NAD^+$ to $NADH + H^+$.$3$. $\alpha$-Ketoglutaric acid $\rightarrow$ Succinyl-CoA: This step is catalyzed by $\alpha$-ketoglutarate dehydrogenase and reduces $NAD^+$ to $NADH + H^+$.$4$. Malic acid $\rightarrow$ Oxaloacetic acid: This step is catalyzed by malate dehydrogenase and reduces $NAD^+$ to $NADH + H^+$.$5$. Succinic acid $\rightarrow$ Fumaric acid: This step is catalyzed by succinate dehydrogenase. In this reaction,$FAD$ is reduced to $FADH_2$,not $NAD^+$. Therefore,$NAD^+$ is not reduced in this reaction.

In which reaction is $NAD^+$ not reduced to $NADH + H^+$?
